SPECIFICATION forming part of Letters Patent No. 781,950, dated February7, 1905, Application filed April 21, 1904- Serial No. 204,214.

To (alt whom it may concern.-

Be it known that I, ELLHSJANNEY, a citizen of the United States,residing in Fairfax county, State of Virginia, have inyented new anduseful Improvements in Car-Couplings, of which the following is aspecification. I My invention relates to-carcouplings, and moreparticularly to that class knownas the Janney type, and has foritsobject to provide certain new and useful improvements over theconstruction disclosed in an application liled by me May 5, 1903, SerialNo. 155,765, as will be hereinafter more definitely described andclaimed.

in the accompanying drawings, Figure 1 is a pQlSpGCSlVQ view of myimproved coupling, showing the samein its closed position, the

the opposite "direction from that of incline 9, the meeting edge 11 ofsaid inclines being on a slight incline upward andforward, as clearlyseenin Figs. 4, 6, and 7; said recess 8 is formed with camsurface 12,inclining in a directiont he'reverseof camsurface 9 and haying its upperend projecting beyond the side face of the pin. As seen in Fig. 7, theupper portion of said cam-surface,

Formed in the side of pin 7 and just below the lower edge of t draw headwhen said pin is in its lowermost position is an incline 23, adapted toperform the fpllowing double function: \Vhen the pin neyjtypc, in whichpin 3, the usual coupling-hook l. l ,Bessing vertically through theupper and l lowerapertures 5 and 6 in the draw-head 2 is l thelpcking-pinY, the same being recessed on its. f'nont side at 8 andhaving the upper facaof said recess formed with a relatively long in- 7is in its lowermost by, the ,Jtraction' on said coupling-hookwill forcethe locking-pin 7 to the right, as shown in Fig. 6, thus causing-incline23 to underlie Patented February '7, 19 05.

' sition, the contact of incline 23 with thelower edge of, the draw-head2 forcing said pin toa 1 the left toward the tail of the coupling-hook,

so that the projeeting end of lowencam-surface 12 will i be thrown moresurely beneath corresponding cam-surface 15 on said coupling-hook tail.v

On the side nearest when in its locked position the pin 7 is recessedvertically at 24;, against which'recess the coupling-hook tail bears,while on the op- I posite side the draw-head is provided witha verticalextension 25, affording an increased bearing-surface for the pin 7 whenunder the tension of the couplinghook, as seen in Fig. 5. I

Pivoted to the upper end of the pin 7 is a 25 link 26, havinga shoulder27 adapted by its contact with the top of the pin to limit the forwardtilt of said link, and ashoulder 28 for limiting its rearward tilt, thesame operating the coupling-hook tail forereferred to' I have. shown pin7 adaptedto be supported saidpinfrom said iiatsurface, 16

to prevent said link from tilting forward be- 3 yond the vertical planeof the pin 7, but permitt'ing a more extended rearward tilt thereto, asshown in Figs. in brackets is an operating-rod 31, having a handle-32 at3 5 its outer. end and anjnner bent arm 33, passing loosely through-thelink 26, said arm being preferably depressed at about its center,

as shown in Fig. 8. I g 7 From the above description the operation 4o'ofmy improved construction will be understood to be as follows: With thepin 7 in its lowe'rmostposition and the coupling-hook 4 open the deviceis ready-for automaticcou'pling, the rotation of said hook causingcamsurface 14 on the tail thereof to contact with cam 9 on the pin 7,and thus raise the latter until the coupling-hook tail passes the same,when it willdrop automatically. and thus lock the hook in its closedposition.

means of rod 31, in the manner, described, until the incline 13 on thepin'engages the incline -17 on'the hook, when by reason of the forwardand upward inclination of the same, as shown in Figs. 4 and 9,theposition shown in Fig. 4,=so that the coup.

1, 4, and 8. :Mounted- 29 on the cross-sill 30 of the car Now when 50-it is desired to uncouple, the pin 7is lifted, by hereinafter While itis preferred lockingpin 7, I have provided the inclines 12 will dropinto.

In the application filed by me and heretothe locking" in the locksetposition ,by means of ia shallow recess or seat inthe draw-head;andd'a'n i mportant feature of the present inventibuis to deepen-thisrecess-orseat; so that the pin 'maynotbe accidjently displaced?therefrom and at the same tii'nex'te provide means for positivelylifting a v its engagementtherewithduring theirotation of thecoupling-'hookto the open; or closed position. This object'I-acomplish-.-

by providing theshortinelineflO onthe pin,

which forms, in conjunction withthe'incline 9 thereomi'the edge 11,inclined upwardly and-"8.9 forwardly; 'Now as the cou'plinghookstarts torotate to ,its o'pen position the upper edge of the frontface of itstail wiilat-oncegcom tact withi-fthe short incline lmfwh'ich i-n thelock-set, positig'in' Ofqthd pin, 'lies' lowerthan I and vwill' raisesaid-pin sufficiently to free the'latter from its engage ment'with therecess or seat2Q, and as the; edge 11 isfreached the upwardand outward jinclination of-jthe same" will" permita'contact 0 between it and surface'lfi only it the? extreme inner portion of. said-edge, or' at the centerof gravity of said pin, thus, causing said pin toresume itsvertical'position and permitting. it'tov drop free from said recessforseat 20 when released. by. the coupling-hook -tail.

7 to incline the'edge 11 as described inorder to accomplish this resuit,the sameeeffect may be obtained by inclining the jflatsurface l6upwardly, so that only its extreme outer end" will contact with the;edge 1], as wilLbereadily understood.

In order to positively rotate the coupling-i Y book 4 to its openposition by means of theand.15, operating asfollowsi When thecoupling-hook is locked,but not engaged by another coupling-hook,thelifting of locking-pin 7 will cause the projecting upper end ofincline 12thereon to engage the incline 15 on the tailofisaidcouplinghook, and the further lifting of said locking-pinnecessarily rotates said coupling-hook to its open position-in a man-'ner readily understood. In order that this engagement'bf the inclinesmay beinsured, l I have providedthe incline 23 on the opposite side ofthe locki'ng-pin'Z, which by its contact with the loweredge of thedraw-head as the locking-pinis raised forces said lockingpin toward thetail of the coupling-hook, as, seen in Fig. 6. By providing the recess24 in the side of locking-pin 7, with which the coupling-hook tailcontacts when locked, I cause said tail to lie more surely in the pathof the incline 12, as also seen in Fig; ,6.

;Referring now to the operation of the pinliftingmechanism, it will beobserved that the link 26, pivoted to the upper end of locking-pin7,loosely embraces the bent arm 33 ofoperating-rod 31 and that said iinkbecause 3 of shoulders 27 and 28 cannot tip forward beyond the verticalposition; though permitted a limited rearward tilt, as seen in Fig. i.It will also be observed that said link 26 is pivoted to the pin 7forward of the transverse vertical center of the latter and that whensaid pin is in its locking position (shown in Fig. 8) said link engagesthe arm 33 at the point of lowest depression of the latter, the resultbeing that. when said arm is lifted by means of handle 32 that portionof said arm in front of the depressed portion will at once begin toassume an upward anglercarryin'g link 26 to the rear, which, togetherwith the forward pivotal point of attachment of said link to the pin 7,will bring the lower end of said pin 7 forward as it is lifted by saidarm 33 and will thus more surely cause an engagement of edge 19 andshoulder 20 to retain the pin 7in the lock-set position. A further andmore important function of the pin-lifting mechanism, however, residesin the fact that owing to the construction of link 26 and lifting-arm 33any breaking of the coupler-bar whereby the coupling is pulied away fromthe car will not break the liftingmechanism, the link 26 passing freelyoff the end of arm 33, leaving the latter intact, which is necessarilynot the case with the chain connections now in use.

By provi with the initial inclination .itwill be seen that as pin islifted above the lock set position to throw the hook open, as" shown inFig. 9, the contact with said inclined surface with the inclined surface20 will immediately tend to force the pin 7 to the rear, this movementbeing increased as the more abrupt inclination 22 is reached, the resultbeing that when said pin 7 is thus lifted'an immediate movement awayfrom the shoulder 20 is begun, which is increased by the incline 22, sothat when said pin is released it will drop. to its lowermost position.This feature functions only when the pin 7 is lifted to automaticallythrow the hook at open, the tendency of the contact between theinclines. 13 and 17, as well as the point of application of the lift tothe pin, being to force the lower end of the pin forward, whichiseffectually counteracted by the inclines 2O, 21, and 22, which not onlyforce the lower end of the pin to the rear, thereby carrying the rearvertical wall of the recess 8 in the pin away from the path of travel ofthe coupling-hook tail, but also aid in throwing the coupling-hook open.

in order that the pin 7 may have the necessary lateral play withoutcontacting with the end of the coupling-hook tail, 1 deepen the recess 8thereof at 34 to receive the tail of the coupling-hook when in itslocked position. the action of the inclines 20, 21, and 22, abovedescribed, as well as the action of flat surface 16 and edge 11 when thehook is opened with the pin in the lock-set position, being such dingthe rear face 21 of recess 18' that the pin 7 will be forced rearward,so as to prevent any contact vertically between said pin and the end ofthe coupling-hook tail as the latter moves to the open position. therebypreventing any possible binding between these parts during thismovement.

In Fig. I haveshown a slightly-modified construction, the recess or seatinstead of being formed in the wall of the draw-headboing replaced by aremovable cross-bar 35, with which the inclined edge 19 engages tomaintain the locking-pin in the lock-set position, the rounded surfaceof said cross-bar performing the function of the incline 20. Byemploying said cross-bar 'lodgment of dirt at thispoint is prevented,and, furthermore, the usual cotter-pin for preventing completewithdrawal of the pin 7 from the draw-head may be dispensed with, saidcross-bar projecting sniiicicntl y far in the aperture 6 to prevent thepassage of the lower end of the pin, it being understood that saidcross-bar is to be inserted 7 after the pin 7 has been located inposition.

\Vhile I have illustrated and described the coupling-hook as providedwith a flat surface 16 on the upper face of its tail, such construc-'tion is not a necessary feature, the device operating equally as wellwith the incline 14: extenlded to the front face pf the coupling-hooktai -Having thus described my invention, what. i

I claim as new, and desire to secure by Letters Patent, is

1. In a car-coupling, the combination with the draw-head, of acoupling-hook pivoted therein and having inclines in reverse directionson the upper and under sides of its tail, and a vertically-movablelocking-pin for said coupling-hook having inclines similar to those onthe tail of the coupling-hook, and also having an additional upperincline the reverse of the main incline. v

2. In a car-coupling, the combination with the draw-head, and acoupling-hook pivoted having an incline adapted to be engaged by theupper edge only of the front face of the coupling-hook tail as thelatter moves to the open position, whereby said pin is lifted.
